Polypyrrole metal-phthalocyanine

Transition metal compounds, such as organic macrocycles, are known to be good electrocatalysts for oxygen reduction. Furthermore, they are inactive for alcohol oxidation. Different phthalocyanines and porphyrins of iron and cobalt were thus dispersed in an electron-conducting polymer (polyaniline, polypyrrole) acting as a conducting matrix, either in the form of a tetrasulfonated counter anion or linked to... 

Through examples of new catalyst of this class could be mentioned polymeric complexes such as Co-polypyrrole complex [13], Mn-polypyrol-phthalocyanine complex [14], Co(II)-tetrasulphophtalophthalocyanine complex [17]. Active center of this catalyst is the metal ion encircled with nitrogen atoms. The structure of Mn-polypyrol-phthalocyanine complex (MnTPhPyrPc) is showed in Fig. 2. 

Anionic metal complexes, such as tetrasulfophthalocyanine or disulfoferrocene, can be incorporated from solution during the oxidative eleetro-chemical polymerization of pyrrole [24-27]. After re-reduction of the polypyrrole film the phthalocyanine derivative remains in the film, and the observed electrochemical conductivity is explained by ion transport of small electrolyte cations [26]. 

Polypyrrole was modified by incorporating phthalocyanine tetrasulfonic acid RuOj and several metals . More flexible films were obtained by the synthesis...
